Technical Field

[0001] This application belongs to the field of valve technology, and more specifically, relates to a temperature-regulating outlet valve. Background Technology

[0002] The outlet valve is one of the important components in a wall-hung boiler system for achieving water circulation. The outlet valve is often connected to heating pipes and heat exchangers to distribute water flow.

[0003] In related technologies, traditional wall-hung boilers typically have a bathroom hot water outlet valve, which is usually connected to the bathroom flow channel of the heat exchanger. Under this design, the hot water flowing out of the bathroom hot water outlet is the hot water generated by the heat exchanger. However, when the boiler's power is high, the temperature of the hot water generated by the heat exchanger often increases accordingly, resulting in excessively hot water flowing out of the bathroom hot water outlet. This affects the user experience and poses a risk of scalding, necessitating improvement. Utility Model Content

[0004] In view of the deficiencies or improvement needs of the existing technology, this application provides a temperature readjustment outlet valve, which aims to adjust the water temperature in the bathroom hot water outlet circuit when it is too high.

The cold water inlet is connected to the bathroom hot water channel. The bathroom hot water channel has a temperature regulating section for mixing and regulating the temperature of cold water flowing in from the cold water inlet and hot water flowing in from the bathroom hot water inlet.

[0007] Compared with the prior art, the present application's technical solution provides a cold water outlet on the main body of the outlet valve and leaves a temperature regulation section in the bathroom hot water channel for mixing and regulating the temperature of cold and hot water.

[0011] As a further preferred embodiment, the outlet valve also includes a mixer for mixing cold and hot water, which is disposed in the temperature control zone.

[0012] As a further preferred embodiment, the mixer has a mixing channel through which the water supply flows, and the mixing channel is provided with a mixing structure for agitating the water flow.

[0013] As a further preferred embodiment, the mixing structure is disposed at the inlet of the mixing channel, and the inner wall of the mixing channel cooperates with the mixing structure to form a multi-channel turbulence section. The mixing channel also has a single-channel confluence section, which is connected to the multi-channel turbulence section.

[0014] As a further preferred embodiment, the water mixing structure is a spiral flow guiding structure.

[0015] As a further preferred embodiment, the spiral guide structure includes a central reinforcing member and multiple spiral blades. The central reinforcing member is coaxial with the housing of the mixer, and the multiple spiral blades are distributed circumferentially along the central reinforcing member and connected between the central reinforcing member and the housing of the mixer.

[0017] As a further preferred embodiment, the outlet includes a plurality of lateral outlets formed on the circumferential surface of the mixer housing, and / or an end-face outlet formed on the end face of the mixer housing.

[0018] As a further preferred embodiment, the outer surface of the mixing device's housing fits snugly against the inner circumferential wall of the mixing channel, and the mixing device is detachably connected to the main body of the outlet valve.

[0019] In summary, compared with the prior art, the technical solutions conceived in this application have the following main technical advantages:

[0020] 1. This water outlet valve has a cold water inlet on the valve body and a mixer for mixing cold and hot water in the bathroom hot water channel, so that the cold water entering through the cold water inlet can neutralize the hot water entering through the bathroom hot water inlet, thereby achieving temperature regulation of bathroom water.

[0021] 2. The mixing device built into this outlet valve has a spiral flow guiding structure. The water flowing through the spiral flow guiding structure will generate a spiral, which will stir the water flow and promote the mixing of hot and cold water.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a temperature-regulating outlet valve. (Refer to...) Figure 1-2 The temperature readjustment outlet valve includes an outlet valve body 1, which includes a bathroom hot water outlet path formed by a bathroom hot water inlet 2, a bathroom hot water channel 3, and a bathroom hot water outlet 4. The bathroom hot water inlet 2 is used to connect to a heat exchanger. The outlet valve body 1 is also provided with a cold water inlet 5 for connecting to an external cold water source. The cold water inlet 5 is connected to the bathroom hot water channel 3. The bathroom hot water channel 3 has a temperature adjustment section for mixing and adjusting the temperature of cold water flowing in from the cold water inlet 5 and hot water flowing in from the bathroom hot water inlet 2.

[0032] Preferably, the cold water inlet 5 and the bathroom hot water outlet 4 are spaced apart. More preferably, the cold water inlet 5 and the bathroom hot water inlet 2 are located on opposite sides of the outlet valve body 1. With this design, the cold water flowing into the cold water inlet 5 and the hot water flowing into the bathroom hot water inlet 2 can form convection and merge into the bathroom hot water channel 3 to improve mixing efficiency. Furthermore, the incoming cold and hot water can be mixed and temperature-regulated in the bathroom hot water channel 3 before flowing to the bathroom hot water outlet 4, ensuring that the water flowing out of the bathroom hot water outlet 4 has a relatively uniform and suitable temperature.

[0033] Furthermore, in some embodiments, the outlet valve also includes a temperature sensor 6 for detecting the water flow temperature at the bathroom hot water outlet 4. For example... Figure 1 In the illustrated embodiment, a sensor interface is provided in the bathroom hot water channel 3, close to the bathroom hot water outlet 4, and a temperature sensor 6 is installed at this sensor interface to effectively monitor the temperature changes at the bathroom water outlet. The temperature sensor 6 may include, but is not limited to, an NTC sensor.

[0034] Furthermore, in some embodiments, the outlet valve also includes a control valve for adjusting the opening and closing of the cold water inlet 5. By controlling the cold water flow rate of the cold water inlet 5 through the control valve, the water temperature at the bathroom hot water outlet 4 can be flexibly adjusted, making it convenient to obtain hot water at a suitable temperature.

[0035] Furthermore, in some embodiments, the outlet valve also includes a mixer 7 disposed within the temperature control zone for mixing cold and hot water. The addition of the mixer 7 enables faster and more uniform mixing of cold and hot water in the outlet valve.

[0036] Specifically, such as Figure 2 As shown, in some specific embodiments, the mixing device 7 includes a housing 7-1, the outer surface of the housing 7-1 is fitted to the inner peripheral wall of the bathroom hot water channel 3, a mixing channel through which the water supply flows is formed in the housing 7-1, the mixing channel has an inlet and an outlet, and a mixing structure for agitating the water flow is provided in the mixing channel.

[0037] In some embodiments, a mixing structure is disposed at the inlet of a mixing channel. The inner wall of the mixing channel cooperates with the mixing structure to form a multi-channel turbulence section. The mixing channel also has a single-channel confluence section, which is connected to the multi-channel turbulence section. This design enables the mixing and confluence of water flows, promoting the mixing of cold and hot water.

[0038] Of course, in some embodiments, a single-channel confluence section may not be provided in the mixing channel. In other embodiments, the mixing structure may be located in other positions in the mixing channel, such as at the outlet of the mixing channel, as long as the location is sufficient for the mixing structure to achieve the effect of disturbing / stirring the water flow.

[0039] Furthermore, in some embodiments, the mixing structure includes, but is not limited to, a spiral flow guide structure, such as a mesh structure, a porous structure, or a staggered baffle structure. When a spiral flow guide structure is selected, the water flowing through the spiral flow guide structure will generate a spiral, which will stir the water flow and promote the mixing of hot and cold water.

[0040] For ease of understanding, Figure 3-4 A spiral flow guiding structure is shown, which includes a central reinforcing member 7-2 and multiple spiral blades 7-3. The central reinforcing member 7-2 is coaxially arranged within a housing 7-1, and the multiple spiral blades 7-3 are distributed circumferentially along the central reinforcing member 7-2 and connected between the central reinforcing member 7-2 and the housing 7-1 of the mixing device 7.

[0041] The area enclosed by the central reinforcing member 7-2, the helical blade 7-3, and the inner wall of the shell 7-1 is the multi-channel turbulence section; the section of the shell 7-1 away from the helical blade 7-3 is the single-channel confluence section. Generally, the central reinforcing member 7-2 is a rod, and the central reinforcing member 7-2, the helical blade 7-3, and the shell 7-1 are preferably manufactured using an integral molding process.

[0042] Furthermore, in some embodiments, in order to ensure that the water in the mixing valve 7 can be discharged smoothly, the mixing channel can be provided with multiple outlets, and at least one outlet is connected to the bathroom hot water outlet 4.

[0043] In some embodiments, the water outlet includes a plurality of lateral water outlets 7-4 formed on the circumferential surface of the housing 7-1 of the mixer 7, and / or end-face water outlets 7-5 formed on the end face of the housing 7-1 of the mixer 7. Generally, the form and number of water outlets can be selected and designed according to the layout of the bathroom hot water outlet 4 and the mixer 7.

[0044] For example: in some bathroom hot water outlet 4 and mixing valve 7 are not coaxial (such as...) Figure 2 In the layout shown (where the hot water outlet 4 is located around the mixer 7), a side outlet 7-4 can be connected to the hot water outlet 4. In some designs where the cold water outlet 5 is coaxially connected to the mixer 7, an end outlet 7-5 can be connected to the hot water outlet 4.

[0045] Furthermore, in the water mixer 7 used in this embodiment, the water mixer 7 is provided with both a side outlet 7-4 and an end outlet 7-5, and the water mixer 7 is detachably connected to the water outlet valve body 1.

[0046] Specifically, in this embodiment, as Figure 2As shown, the main body 1 of the water outlet valve is provided with an interface 8 that connects to the bathroom hot water channel 3. A plug 9 is detachably connected to the interface 8. The inner wall of the bathroom hot water channel 3 forms a limiting surface along the circumference, which is used for the mixing device 7 to be positioned by contact.

[0047] When assembling the mixer 7, install the mixer 7 into the bathroom hot water channel 3 along the interface 8, so that the end of the mixer 7 with the water inlet abuts against the limiting surface. Then, install the plug 9 to the interface 8, seal the interface 8 with the plug 9, and position the end of the mixer 7 with the end face water outlet 7-5 with the plug 9 to complete the assembly of the mixer 7.

[0048] It should be clarified that the main body 1 of the water outlet valve disclosed in this embodiment can be selected from existing structures well known in the art, such as the stepper motor water outlet valve disclosed in patent document CN218718986U.
